From a0e5a12fd18d47aa87a7a8c60ca5bc422b136564 Mon Sep 17 00:00:00 2001 From: Roger Tseng <rogerable@realtek.com> Date: Tue, 12 Nov 2013 15:11:40 -0800 Subject: [PATCH] drivers/memstick/core/ms_block.c: fix unreachable state in h_msb_read_page() In h_msb_read_page() in ms_block.c, flow never reaches case MSB_RP_RECIVE_STATUS_REG. This causes error when MEMSTICK_INT_ERR is encountered and status error bits are going to be examined, but the status will never be copied back. Fix it by transitioning to MSB_RP_RECIVE_STATUS_REG right after MSB_RP_SEND_READ_STATUS_REG.
